Experimental α-stage • Apache-2.0
Icing runs a Noise-XK handshake, Codec2 and 4-FSK modulation over the plain voice channel, so any GSM/VoLTE call can be upgraded to private, authenticated audio - no servers and no IP stack required.
See docs/Icing.md for protocol goals, threat model, and technical architecture.
# on an Android phone (Android 12+)
git clone https://git.gmoker.com/icing/monorepo
cd dialer
# Requires Flutter and ADB or a virtual device
flutter run
⚠️ This is an alpha prototype: expect crashes, missing UX, and incomplete FEC.

- [DryBox Only] Noise XK handshake (X25519, AES-GCM, SHA-256)
- Static keys = Ed25519 (QR share)
- [DryBox Only] Voice path: Codec2 → encrypted bit-stream → 4-FSK → analog channel
- GSM simulation in DryBox for off-device testing

What is Monero ? Monero is a secret money. Nobody knows how much you have, you transfer, or whom you transfer it to. True privacy, true ownership, true money.
